Summary:To suppress or avoid occurrence of engine stall while suppressing responsiveness in starting an engine from deteriorating, when executing rapid garage control and engine starting control at the same time.SOLUTION: When rapid garage control and engine starting control are executed at the same time, a clutch is controlled so that packaging can be completed during transition of the rapid garage control, and the clutch is controlled so that cranking torque is transmitted to the clutch after a rotation speed of an electric motor is increased up to a second predetermined rotation speed predetermined in order to avoid occurrence of engine stall or higher during the engine starting control, which enables engagement operation of the clutch to progress until right before cranking by the clutch so that the clutch does not have a torque capacity, until the rotation speed of the electric motor is increased up to the second predetermined rotation speed or higher.SELECTED DRAWING: Figure 5 【課題】急速ガレージ制御の実行とエンジン始動制御の実行とが重なる際に、エンジン始動の応答性の低下を抑制しつつエンジンストールの発生を抑制又は回避する。【解決手段】急速ガレージ制御の実行とエンジン始動制御の実行とが重なる場合には、急速ガレージ制御の過渡中にパック詰め完了状態とするようにクラッチが制御されると共に、電動機の回転速度がエンジン始動制御の際にエンジンストールの発生を回避する予め定められた第２所定回転速度以上に上昇させられた後にクランキングトルクをクラッチが伝達するようにクラッチが制御されるので、電動機の回転速度が第２所定回転速度以上に上昇させられるまでは、クラッチがトルク容量を持たない範囲でクラッチによるクランキングの直前までクラッチの係合作動が進行させられる。【選択図】図５
